Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing security update 5012666 or cumulative update 5012650. It is, therefore, affected by multiple vulnerabilities:

- A remote code execution vulnerability. An attacker can exploit this to bypass authentication and execute unauthorized arbitrary commands. (CVE-2022-26812, CVE-2022-26919,CVE-2022-26809,CVE-2022-26918,CVE-2022-26813, CVE-2022-26821,CVE-2022-26819,CVE-2022-26815,CVE-2022-26916, CVE-2022-26822,CVE-2022-26917,CVE-2022-26829,CVE-2022-26820, CVE-2022-24541,CVE-2022-24492,CVE-2022-24536,CVE-2022-24534, CVE-2022-24485,CVE-2022-24533,CVE-2022-26903,CVE-2022-24528, CVE-2022-21983,CVE-2022-24500)

- An elevation of privilege vulnerability. An attacker can exploit this to gain elevated privileges. (CVE-2022-26796, CVE-2022-26827,CVE-2022-26802,CVE-2022-26797,CVE-2022-26807, CVE-2022-26792,CVE-2022-26794,CVE-2022-26803,CVE-2022-26801, CVE-2022-26787,CVE-2022-26810,CVE-2022-26904,CVE-2022-26798, CVE-2022-26790,CVE-2022-24544,CVE-2022-24540,CVE-2022-24481, CVE-2022-24527,CVE-2022-24474,CVE-2022-24521,CVE-2022-24499, CVE-2022-24494,CVE-2022-24542,CVE-2022-24530)

- A denial of service (DoS) vulnerability. An attacker can exploit this issue to cause the affected component to deny system or application services. (CVE-2022-26915, CVE-2022-26831,CVE-2022-24538,CVE-2022-24484,CVE-2022-26784)

- An information disclosure vulnerability. An attacker can exploit this to disclose potentially sensitive information. (CVE-2022-24493,CVE-2022-24498,CVE-2022-24483)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Apply Security Update 5012666 or Cumulative Update 5012650

Before running any exploit against any system, make sure you are authorized by the owner of the target system(s) to perform such activity. In any other case, this would be considered as an illegal activity.

WARNING: Beware of using unverified exploits from sources such as GitHub or Exploit-DB. These exploits and PoCs could contain malware. For more information, see how to use exploits safely.
